Information about how the answer checker works.
If you're a teacher who is interested in seeing how the answer checker works, you might want to try the demonstration first. If you're a physics teacher and want to see how it works on some physics examples, you could also download one of my free books, pick a homework problem out of the book, and try entering correct and incorrect answers in Spotter. (The full text of the physics problems is not displayed by Spotter.) Math teachers might be interested in some of the MOB tests --- these do include the full text of the problems.
